Good to know

Stability and motion control add-ons are uncommon for workout shoes and are never present in CrossFit or weightlifting footwear. They are mostly found in walking shoes where the gait is easier to correct.

Weight

Weight

Training footwear typically weighs between 200g and 300g per shoe to accommodate agile workouts. Minimalist trainers go as low as 150g, while weightlifting shoes can go as high as 500g.

The Nike Train Ultrafast Flyknit is part of Nike's wide selection of training shoes. This particular model was designed with agile training in mind. It features a lightweight and breathable Flyknit upper to aid the speed of movement.

The Chainlink-shaped Flyknit on the midfoot is interlaced with the Flywire cables to provide a secure lockdown fit. The mid-cut construction gives additional support to the ankle.

The shoe makes use of a low-profile midsole, offering a more grounded and stable positioning of the foot. The forefoot outrigger creates a wide base for stability.

The Flex Speed Plate on the outsole acts as a propulsion panel for a more responsive ride. A variety of rubber pods ensure multidirectional grip and traction.

The Nike Train Ultrafast Flyknit is only available in men’s version. It comes in full and half sizes and runs true to size. The shoe is most suitable for people with medium-sized feet as it is offered in D – Medium width.

The Nike Train Ultrafast Flyknit features a variety of multidirectional triangles throughout the outsole unit. They are made of solid rubber to provide grip and traction on different indoor surfaces. The heel and forefoot sections are reinforced with patterned rubber pods for enhanced traction and durability.

A lightweight carbon fiber compound, or the Flex Speed Plate, stretches from the midfoot to the forefoot. Its purpose is to deliver propulsion and energy return during the toe-off for a faster movement.

A low-profile midsole is employed in the Train Ultrafast Flyknit. It places the foot closer to the ground for a more stable underfoot feel. A forefoot outrigger extends past the upper on the lateral side to offer a broader base and enhanced lateral stability.

The midsole unit is made of the lightweight ethylene-vinyl acetate (EVA) foam. It is engineered to provide basic cushioning while being dense enough to assist rapid changes in direction. It is also tough, serving as an outsole in some areas, reducing the overall weight of the shoe.

The renowned Flyknit material makes up the upper unit of the Nike Train Ultrafast Flyknit. It is tightly-woven in the rearfoot section and at the toe box where more structure is needed. Additional support in the ankle is delivered by the mid-cut design of the upper.

In the midfoot section, the innovative Chainlink-shaped Flyknit is utilized. It is interconnected with the Flywire cables to form a responsive containment system for the foot. This design takes cues from a Chinese finger trap mechanism, so it keeps the foot more locked-in. The layer underneath the “chain link” is made of a lightweight, transparent mesh.

The Flywire cables are interconnected with the lacing system. When the laces are pulled, the filaments become taut and provide a more secure and customized fit.
